A major advancement in understanding the factors underlying wildlife-habitat relationships, Applications for Advancing Animal Ecology will be an invaluable resource to natural resource management professionals and practitioners, including state and federal agencies, non-governmental organizations, and environmental consultants.

This book provides expert evaluation of the use of video techniques in a wide range of behavioural and ecological research situations. Covering applied techniques both in the laboratory and the field, the latest results from leading expert researchers are given

AbstractTracking technology has been heralded as transformative for animal ecology. In this paper I examine what changes are taking place, showing how current animal movement research is a field ripe for philosophical investigation. I focus first on how the devices alter the limitations and biases of traditional field observation, making observation of animal movement and behaviour possible in more detail, for more varied species, and under a broader variety of conditions, as well as restricting the influence of human presence and observer bias. I reconstruct these as shifts in scope, objectivity, accuracy and fruitfulness. The second transformation is slightly less obvious but equally significant for animal ecology. Tracking devices generate complex data that demands both statistical and biological expertise, which has led to increasingly frequent and intensive collaborations between statisticians and biologists. Based on interviews, I examine how researchers in these interdisciplinary collaborations negotiate the collection, analysis and interpretation of movement data, integrating research interests, methodological constraints, previous field observations, and background theory. Tracking technology is therefore also shifting which disciplinary considerations are brought to bear on research into animal movement and behaviour and how this research is conducted.

This book continues the authoritative and established sequence of theoretical ecology books initiated by Robert M. May which helped pave the way for ecology to become a more robust theoretical science, encouraging the modern biologist to better understand the mathematics behind their theories.

Examines the efforts made by scientists in the fields of environment, environmental protection, and environmental science. Covering a range of topics - including the Earth sciences, atmosphere, oceans, ecology, animals, plants, and exploration - this title provides a panorama of accounts of particular discoveries and the people who made them.

This book deals with the role of education in improving animal welfare and reducing animal suffering inflicted by humans. It embraces situations in which humans have direct control over animals or interfere directly with them, but it considers also indirect animal suffering resulting from human activities. Education is regarded in the broad sense of creating awareness and facilitating change. First, consideration is given to a number of specific themes in which education can make an important contribution towards reducing animal suffering, and subsequently an examination is made of a number of interrelated contexts in which education can address the various themes. The considered educational themes are: · animal suffering and sentience that have both scientific and moral aspects · human discrimination against animals known as speciesism and the need for attitudinal change by humans · role and existing limitations of legislation in providing protection to animals · matter of enforcement of animal protection legislation · achievement of reform to improve animal protection by legislative and other means · training of professionals, carers, and users involved with animals to provide better protection · the scope for science to contribute to improved animal protection · animal protection as a regional and international issue

The book includes 22 chapters by 28 authors united by the single theme: biogeography and ecology of Bulgaria. From the single-celled organisms in the Black Sea sand to the endemic cave crustaceans, from the mountain glacial relict insects to the most diverse bird fauna in Europe, the unique fauna of Bulgaria has been a subject of study of mostly Bulgarian zoologists for more than a century. This is the first monograph in English broadly addressing all vertebrate and many key invertebrate groups of Bulgaria, their faunistics, origin, geographical and ecological distribution, and conservation issues are addressed by the experts on each group.
